MACHINE FOR CREASING AND BLEACHING LEATHER FOR HARNESS.

Specification forming part of Letters Patent N o. 21,989, dated November 1858; Ressued May 31,

`Straps and Blacking the Edges Thereof;

and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a vpart of this specification, in which- Figure l, is a. vertical central section of my invention. Fig. 2, is a transverse section of ditto, taken in the line m, Fig. 1. Fig. 3, is a horizontal section of ditto, taken in the line y, y, Fig. 1. Fig. 4, is a transverse section of ditto, taken in the line a, e, Fig. 3.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in the employment or use of creasing and embossing rollers and a pressure roller combined and arranged with two color fountains provided with felt distributers the whole being arranged substantially as hereinafter shown for creasing, embossing and coloring the edges of leather straps.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a suitable framing on the upper part of which two heads B, B', are placed, between which a frame C, is placed, the frame working on pivots a, a, projecting from the inner sides of the heads B, B. To the outer end of the frame C, a treadle D, is connected by a strap E, and in the inner end ofthe frame C, at the opposite side of the pivots ci, a, a roller F, is fitted, said roller being allowed to turn freely in its frame. The roller F, is toothed at one end, as shown at b, and said teeth gear into a wheel c, which is placed on one end of a roller G, said roller having one of its jour nals fitted in the head B, and the other journal fitted in a pendent H, attached to the end of a horizontal bar I, which is secured to the upper end of the head B', see Fig. 2.

In the frame C, there are placed two gages d, cl, which are secured therein by set screws e, e. These gages have their inner ends curved and they project over the roller F. Each gage having a bar or plate j", attached the object of which will be presently explained. The outer parts of the gages d, d', are fitted in a slot or opening g, in the frame. J, is a spring which is attached to the framing A, and bears against the under side of the frame C, as shown in Fig. l.

On the roller G, there are placed two collars la., zf, and on both ends of each collar a roller z, is formed or attached, said rollers having their outer edges or parts milled `or formed as shown at j, so as to produce ornamental embossed lines on the strap, see Fig. 2. The inner edges or parts of the rollers are groovedY as shown at 7c, so as' to crease the strap, as will be hereinafter more particularly referred to. To the head B, a plate Z, is attached, said plate being slightly inclined and serving as a guide or support to the strap, properly conducting or guiding the same to the rollers which operate upon it.

On the front part of the framing A, there are placed two boxes K, L, in which the usual or any proper colorin substance m, is placed. In each box there is placed a roll of felt M, said rolls projecting up above the inner sides ofthe boxes. The felt rolls M, are saturated with the coloring substance m, and their upper edges or surfaces are kept charged therewith by capillary attraction. To the box K, a bar N, is attached by a hinge or joint a. This bar serves as a weight and keeps the strap in proper position as.it passes through the machine. O, is a bar which serves as a support or bearing for the strap.

The operation is as follows: The strap shown in red and designated by D', is placed over the bar O, and under the weight or bar N, and passes between the saturated felt rolls M, M, and then between the guides d, d', and between roller F, and the inner rollers z', z', of the collars L, L, the collars L, L, being keyed on the shaft G, and the guides d, d. being adjusted in line with the collars l, k', and the boxes K, L, are also adjusted in line with the collars. The box K, guide d, and collar h, may be adjusted; the other box, guide and collar need not be shifted. This adjustment of the above named parts is necessary to admit of straps of varying widths being operated upon. The edges of the straps are colored by the felt rolls M, and the edges of the strap are creased by the grooved edges la, of the' rollers -the strap spreadinlaterally. The guides d, cZ, therefore per orm an important function, forif the straps are allowed to-eX- pand laterally under the pressure ofthe rollers the eflicacy of the machine Would be destroyed at once. The'strap is made to enter between the rollers `by :turning` the crank attached to the shaft G. L

I would remark that-'the :pressure roller as well as the creasing Aand embossing rollers and shaft Gr, are of'metal. In fact all the working parts are of metaLA l l y From 'the vabove description it` will' be seen that straps may be creased andI eln-V bossed in an expeditious and perfect manner, and various forms of rollers-, may be used according` to the nature of the work to be performed5 so that straps may becreascd withoutbeingembossed. f

In the drawings rollers z', are made on each end of each collar so that the collars may be reversed on the shaft G, for eecting a change .of Work.

I claimas new and desire to secure by Let- The pressure roller F, and the creasing and embossingrollers z', in combination With the color fountain "K, L, "and felt'rolls M, M,

the .wholebein-g arranged to operate as and fory the purpose set forth. l,
